Alinhamento de Padrões

Common Core - Math

• 4.NF.A.1

• Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

• 3.NF.A.3d

• Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

• 3.NF.A.3c

• Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram.

• 3.NF.A.3b

• Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model.

• 3.NF.A.3a

• Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.

• 3.NF.A.3

• Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

• 3.NF.A.2

• Understand a fraction as a number on the number line; represent fractions on a number line diagram.
